what is the chemical equation of photosythesis ( Write in chemical equation and word form.)
Explanation:
6CO2 + 6H2O => C6H12O6 + 6O2
During photosynthesis, carbon dioxide gas and water reacts in the presence of sunlight to produce glucose and oxygen gas.
Explanation:
[tex]\tt{6CO_2 + 12H_2 O→C_6 H_{12 }O_6+ 6O_2+ 6H_2 O}[/tex]
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.
how do they treat patients with diabetes? where does the insulin come from? and how do people get insulin? help me please
People with diabetes need to take insulin to help process the sugar, or they can't use it and it stays in their blood. The insulin allows sugar into the cell to be used, which is why diabetics need to take insulin. Insulin is usually prescribed by a medical professional.

b) 80mm and 120 mm of Hg
c) 120 and 120 mm of Hg
d) 80 and 80mm of Hg
Answer:
A
Explanation:
Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure

what is number 9 and 11
Answer:
still 9 and 11. No operations are happening
Explanation:
If number of electrons in an atom is 8 and number of protons is also 8, then
(i) what is the atomic number of the atom? and
(ii) what is the charge on the atom?
Answer:
i) 8
ii)0
Explanation:
The equal nos of the electrons and protons means it's not a ion, which makes the atomic number equal to them.
Since it is not an ion, the charge shall be 0 since it is neither positively nor negatively charged. The overall charge of an atom is neutral too.
Answer:
(i) atomic number = number of protons = number of electrons = 8
(ii)atom will be neutral (no charge) because number of protons(+) is equal to the number of
electrons (-).

Which process does an organism use to move LARGE molecules out of a
cell? *
Answer:
Exocytosis
Explanation:
Exocytosis definition and purposes. Exocytosis is the process by which cells move materials from within the cell into the extracellular fluid. Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Identify and describe the three ways the mutations affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they, in some cases, may have no noticeable affect.
Explanation:
Answer:
Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.
Explanation:
Which macromolecule makes up the main structure of the cell membrane?
Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
The main structure of plasma membrane is made up of lipids.
What is a cell membrane?A membrane is what separates a cell's internal environment from its external environment.It has selective permeability.It is made up of a bilayer of lipids.It contains embedded proteins that may be central or peripheral.Can all molecules cross the plasma membrane?No, all molecules cannot pass through plasma membrane.The compounds that can cross it are small nonpolar molecules or small, charged polar molecules.There are special proteins like carriers, channels etc., that aid in the transportation.What are a few of the plasma membrane's functions?Plasma membrane prevents undesirable and dangerous substances from entering the cell.

investigate the conditions required for seed to germinate. keep the dishes at room temperature for a week.explain your observations
Dry cotton wool
wet cotton wool
covered with water
Explanation:
Starting off, the conditions required for a seed to germinate are:
warm temperatures, so that enzymes can act efficiently.water, for chemical reactions to place.oxygen, for respiration.Observations:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

Explanation:
Jill is blood Type O. She has two older brothers (who tease her like crazy) with blood types A & B. What are the genotypes of her parents with respect to this trait?
Answer:
There you have it. Jill's parents are IAi & IB
Explanation:
one brother: Type B, one of the parents must have the IB allele
other brother: Type A,
other parent must have the IA allele & have a genotype of IAi.
Jill's parents are IAi & IB
Jill's parents have the genotypes IAi and IBi.
What is blood type?Blood type refers to the classification of blood based on the presence or absence of certain antigens on the surface of red blood cells. The most common system used for classifying blood types is the ABO system, which has four types: A, B, AB, and O.
If Jill's blood type is O, then she inherited an O allele from each of her parents. Since her two older brothers have blood types A and B, we can conclude that her parents are both heterozygous for the A and B alleles (IAi and IBi). This means that each parent contributed an i allele to Jill, resulting in her blood type O.
